• MacLayers does not do data validation with packet retry for MacLayers/host internal communication. Thus, poor line conditions may cause a host internal message to be missed. This is usually not catastrophic but means something won't work correctly. For instance a window might not auto-close when a host process death occurs or output might be sent to the wrong window. Downloads, however, are error checked, unless this option has been explicitly turned off by the user.
• The shell TERM variable must have the same value in your layer shells as it does when you initially start layers up.
• If you set the BSD shell TERMCAP variable then that variable must be set in your .login file. It may not be changed to something different in .cshrc.
• The host/MacLayers system attempts to give highest data communication priority to the topmost MacLayers window at all times by throttling down output to other windows. However due to internal UNIX kernel I/O buffering the attempts may not always succeed.
• The "Download Site" folder is kept open after a download which means that if you want to trash that folder you must first choose a new download site or quit MacLayers.
• MacLayers has U.S. keyboard dependencies.
• The layers command will not work properly when being issued from a remote login into the same machine which is already running the initial layers startup command.
• Selecting print when you do not have a printer causes bad things to happen.
